7. Trouble Maintaining Eye Contact
Many people like to maintain their eye contact so as they recognize faces and try to listen and pay attention to what the speaker says. In addition, try to interact with others. For normal kids it is the same thing. Nevertheless, when it comes to those who have autism. It is very different thing.
Because they could not talk to strange, people or even to adults who know them well. They could not respond to people who smile to them even by calling them by their right name. If a kid of your family show this, you have to evaluate him as soon as possible.
